Greenland Mega-Tsunami 2023: 650-Foot Wave Shook Earth for Nine Days
In September 2023, a colossal landslide in Greenland’s Dickson Fjord unleashed the Greenland Mega-Tsunami 2023, a 650-foot wave that reverberated globally for nine days. Captured by the Surface Water and Ocean Topography (SWOT) satellite, this event revealed climate change’s role in destabilizing glaciers, per Earth.com. Kashmir News explores this natural phenomenon.
Details of the Greenland Mega-Tsunami 2023
The Greenland Mega-Tsunami 2023 was triggered by 25 million cubic yards of rock and ice crashing into Dickson Fjord on September 16, creating a wave taller than half the Empire State Building, per Mint. Confined by 3,000-foot cliffs, the wave oscillated as a seiche, sending seismic signals every 90 seconds, per @NASAJPL. Here’s a summary:
| Aspect | Details |
|---|---|
| Date | September 16, 2023, Dickson Fjord. Environment News |
| Cause | Landslide from glacier collapse, 25 million cubic yards. Hindustan Times |
| Wave Height | 650 feet, with seiche oscillations. Breaking News |
| Impact | Damaged research station, archaeological sites. Times of India |
| Seismic Signal | 90-second pulses for nine days, detected globally. |
How SWOT Unraveled the Greenland Mega-Tsunami 2023
The Greenland Mega-Tsunami 2023 baffled scientists until SWOT, a NASA-CNES mission launched in 2022, provided high-resolution data. On September 17, it recorded water tilts up to 1.2 meters, confirming seiche activity, per News18. Machine learning simulated wave behavior, linking it to seismic signals, per @theamynivens.
Climate Change’s Role
The Greenland Mega-Tsunami 2023 was driven by a melting glacier, destabilized by climate change, causing the landslide, per Daily Mail. This event underscores Arctic vulnerabilities, prompting calls for enhanced monitoring, per environment news.
Global Implications
The Greenland Mega-Tsunami 2023 highlights the need for early-warning systems near cruise routes like Dickson Fjord, per Live Science. SWOT’s data could improve disaster preparedness, per technology news.
Why the Greenland Mega-Tsunami 2023 Matters
The Greenland Mega-Tsunami 2023 demonstrated Earth’s interconnected systems, with a fjord event shaking global seismic stations, per India.com. Its recurrence in October 2023 raised concerns about Arctic instability, per @SuzieCanuck. Explore climate impacts in our health section.
